The main objective of this project is to implement the multiple fan beam projection technique using optical fibre sensors with the aim to achieve a high data acquisition rate. Multiple fan beam projection technique here is defined as allowing more than one emitter to transmit light at the same time using the switch-mode fan beam method. For the thirty-two(More)
This paper describes the application and construction of signal sample and hold (S/H) circuit to facilitate data acquisition process using the Keithley Metrabyte DAS 1802HC. A basic tomographic system consists of sensors, signal conditioning circuit, data acquisition system and the creation of suitable computer software to display the reconstructed image(More)
This paper presents the timing advantage of implementing multiple fan beam projection technique using optical fibre sensors for a tomography system. To prepare the optical fibre sensors to be used for this multiple fan beam projection, a collimator is not needed but optical fibre lens' termination is crucial. In this research, the fibre optic lens for(More)
